Have a look at the info page "How do I bind a combination of modifier key
and function key?" under "Key Bindings" in the Emacs FAQ.

Another useful trick is to do the binding interactively with M-x
global-set-key, etc., then use C-x <esc> <esc> (`repeat-complex-command')
to see what it looks like in lisp.

"\C-\M-7" is a correct syntax.

At least your operating system seems to generate something sensible for
this key event.

After typing the keys, do C-h l (`view-lossage') to check what Emacs
_really_ saw.

Try C-h c followed by C-M-7.
